LOUIS PEROTTI, OF NEWARK, NEWV JERSEY.

LIQUID-VDROPPER.

SPECIFICATION forming part of Letters Patent N0. 779,178, dated January3, 1905.

Application filed May 13, 1904. Serial No. 207,863

To all whmn it may concern:

Be it known that 1, Louis PEROTTI, a subject of the King of Italy, and aresident of Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Liquid-Droppers, ofwhich the following is a specification.

The object of the present invention is to provide for a liquid-dropper,and particularly for a device which will permit to discharge the liquidin drops, a teaspoonful, or tablespoonful, according to theprescription. This device has also the object to prevent the liquid frombeing overdosed and the patient or the person handling themedicine-bottle from coming in contact with the said liquid.

My invention consists in the arrangement of a conical funnel having asmall opening at its bottom which causes the liquid contained therein toflow in drops and another opening at one side and at the lower end ofthe funnel. which opening is of a larger size and adapted for thedischarge of a greater quantity of the liquid, as a table-spoonful or ateaspoonful. This second opening is controlled bya suitable valve, sothat the funnel can be used either for the discharge of the liquid indrops, a table-spoonful, or teaspoonful.

The funnel is arranged in such a manner that the same can be readilyapplied to bottles of various sizes and is for this purpose providedwith spring arms suitably attached thereto, the free ends of which areformed to jaws serving as a clasp. The funnel is ap plied to the bottlein such a way that it extends in line with the longitudinal dimension ofthe bottle, and the open top thereof registers with the mouth of thebottle.

In order to make my invention more clear, the same is illustrated in theaccompanying drawings, in which similar numgrals denote similar parts,and in which- Figure l is a vertical section through the liquid-dropper.Fig. 2 is avertical section of the device, taken at right angles to thatshown in Fig. 1; and Fig. 3, a top View thereof.

Referring to the drawings, 1 denotes an ordinary medicine-bottle, thebottom of which is broken away, and 2 the neck of the bottle.

The device forming the subject of the present invention consists of aconical funnel 3, of glass, metal, or any suitable material and of avolume which is exactly equal to that of a table spoon. This funnel hasat its top 4 a circular hole 7, the size of which may correspond withthat of the mouth of a medicinebottle or may be somewhat smaller orlarger than the same. Said funnel 1 is adapted to be applied to the neckof a bottle in such a manner that the top A of the funnel 3 will fitupon the top 6 of the neck 2 and the hole 7 therein will register withthe mouth of the bottle. The bottom of the funnel has a small opening10, which will cause the medicine or the liquid contained therein toflow in drops.

At one side the funnel 8 is provided with an opening 11, serving for thedischarge of the liquid in greater quantities, as a tablespoonful orteaspoonful. This opening 11 is normally closed by a flap-valve 13,suitably applied on the ousicle of the funnel and adapted to turn upon apivot 14. The valve 13 is provided with ahandle 15, extending upward andhaving a spring 16 attached thereto and bearing against the wall of thefunnel. The spring 16 of the handle 15 tends to keep the flap-valve 13always closed. A washer 12 of any suitable material, as rubber or thelike, may be applied to the inner surface of the flap 13 and adapted toform a tight closure of the valve 13.

At each side of the funnel ears 18 are provided, in which wires 17 arefastened, extending upward and forming spring-arms. The latter areprovided at their free ends with jaws 19, of sheet metal or the like,serving as a clasp. The free ends of the jaws 19 are slightly bentoutward, as seen from Fig. 3, thus permitting them to readily engage theneck of medicine-bottles of various sizes.

As stated above, the funnel is of such a size that its volume will beexactly equal to that of a table-spoon. At the outside or inside of thefunnel a mark 20 may be provided at the point at which the volume of thefunnel measured from the bottom thereof to said mark will be exactlyequal to the volume of a teaspoon.

It will be seen that when the funnel will be entirely filled it willcontain just a tablespoonful of the liquid, and when the same will bepartly filled just up to the abovestated mark a teaspoonful of theliquid will be contained within the funnel, so that on opening the valve13 the desired quantity of the liquid will be always discharged,

The funnel may be made in two different colors on its outside, so as todistinctly show the diflerent volumes of a tableand a teaspoonful.

The top opening 7 of the funnel may be provided with a flap-valve 8,having a handle 9 to be operated from the outside, which valve isadapted to close the said opening 1 when the funnel has been filled withthe desired quantity of the liquid. In order to forma tight jointbetween the adjacent surfaces of the top 4 of the funnel and the top 6of the neck 2 of the bottle, a washer 5, of any suitable material andhaving a central hole corresponding with that of the opening 7, may beapplied to the top of the funnel.

I do not confine myself to the arrangements shown, as any change can bemade in the various parts of the liquid-dropper of the present inventionwithout departing from the spirit of the latter.

What I claim, and desire to secure by Letters Patent, is

1. In a medicine or liquid dropper, the combination with a conicalfunnel to be applied to bottles of various sizes, having a small openingat the bottom of the funnel and a larger opening at one side of thefunnel, of a flapvalve for said side opening, a spring tending to closethe valve, a handle for the operation of the said flap-valve, and meanswhereby the funnel can be removably applied to bottles of various sizes,substantially as set forth.

2. In a medicine or liquid dropper, the combination with a conicalfunnel to be removably applied to bottles of various sizes, and having asmall opening at the bottom and a larger opening on one side of thefunnel, the volume of said fun'nel being exactly equal to that of atable-spoon, of spring-arms attached to said funnel, said arms havingtheir free ends formed to jaws which serve as a clasp adapted to engagethe neck of the bottle, a valve adapted to close the side opening, meansfor operating said valve, the funnel being pro- ,vided with a markthereon to distinctly show "the different volumes of the funnel,substantially, and for the purpose as specified.

3. In a medicine orliquid dropper, the combination with a conical funneladapted to contain a table-spoonful of the liquid when entirely filled,or a teaspoonful when partly filled, and having an opening at one sideof the funneLthrough which a tableor tea-spoonful of the liquid can bedischarged, a valve "to close up said opening, a handle for theoperation of said valve, a spring tending to close "the valve, a secondvalve at the top of the funnel adapted to close said top when the funnelhas been filled with the desired quantity of the liquid, substantiallyand for the purpose as specified.
